The best way for a business analyst to gain the end users' cooperation is to identify key stakeholders and develop relationships with them as a trusted advisor; involve stakeholders and end users in the design of the new solution; and act as a liasion between business and technical teams. This will help them understand their needs and expectations, demonstrate value and benefits, and facilitate communication and feedback.
Responding to end users with empathy and accommodate their needs; translating the end users' needs into technical requirements; and delivering the project to the developers to implement the solution may be too reactive or passive without addressing the root causes of resistance or ensuring alignment. Using an assertive influencing style; demonstrating authority and expertise; outlining the project objectives; and making sure end users know that the decision has been made and the time to make changes has passed may be too aggressive or authoritative without building trust or rapport.
